PSECAS: A physical unclonable function based secure authentication scheme for Internet of Drones

Internet of Drones (IoD) is a thriving technology that has found its application in various fields ranging from civilian to military and industries, empowering users to efficiently perform stren-uous operations. However, there are multitudinous security concerns in an IoD environment, such as a drone having to exchange vital information with the control station server and respective users over an open unsecured wireless channel. It is indispensable to ensure the security of this sensitive information, on account of which a Physically Unclonable Function (PUF)-based Secure Authentication Scheme for the Internet of Drones (PSECAS) has been suggested in this paper. The security of the proffered scheme has been ensured under the ROR model and AVISPA simulation. Moreover, informal analysis demonstrates that PSECAS fulfills the necessary security re-quirements and is safe against various adversarial attacks. Finally, a rigorous comparison of PSECAS with other subsisting schemes exemplifies the robustness and superiority of our scheme.
